+# Complete Docker + Traefik + SSL Setup for Quixotic
+
+## Files Created/Modified
+
+### Docker Configuration
+- `docker-compose.yml` - Main orchestration with Traefik v3.0 + Certbot
+- `Dockerfile` - Multi-stage build, fixed ARM64 ffmpeg compatibility 
+- `.env.docker` - Environment variables for production
+- `traefik.yml` - Static Traefik configuration
+- `.dockerignore` - Docker build exclusions
+- `Dockerfile.base` - Base image (created but not used)
+
+### SSL Setup
+- `ssl-setup.sh` - Automated SSL setup script for domains
+- Traefik configured for HTTP challenge (not TLS challenge)
+- Certbot service for additional certificate management
+- Auto-renewal every 12 hours
+
+## Key Features Implemented
+
+### Traefik Reverse Proxy
+- Automatic HTTPS with Let's Encrypt
+- HTTP to HTTPS redirect
+- Dashboard on port 8080 with basic auth
+- Docker provider with label-based routing
+
+### Docker Optimization
+- Multi-stage build for smaller images
+- Health checks for application
+- Persistent volumes for SSL certs and downloads
+- Non-root user for security
+
+### SSL/TLS
+- HTTP challenge for certificate validation
+- Automatic certificate renewal
+- Domain-based configuration via environment
+
+### Architecture Fixes
+- Fixed ffmpeg ARM64 compatibility issue
+- Changed from copied binaries to Alpine packages
+- Proper paths: `/usr/bin/ffmpeg` instead of `/usr/local/bin/ffmpeg`
+
+## Usage Commands
+
+```bash
+# Local development
+docker-compose --env-file .env.docker up -d
+
+# Production with SSL
+./ssl-setup.sh yourdomain.com your-email@domain.com
+
+# Management
+npm run docker:up
+npm run docker:down  
+npm run docker:logs
+npm run docker:rebuild
+```
+
+## Access Points
+- App: https://yourdomain.com (or http://localhost)
+- Traefik dashboard: http://localhost:8080
+- Health check: /health endpoint
+
+## Issues Resolved
+1. ❌ ffmpeg architecture mismatch (ARM vs x86_64)
+   ✅ Fixed with Alpine packages instead of copied binaries
+   
+2. ❌ npm ci lockfile sync issues
+   ✅ Changed to npm install + npm prune
+
+3. ❌ SSL certificate complexity
+   ✅ Automated with Traefik + Let's Encrypt + HTTP challenge
+
+4. ❌ Verbose logging in SoundCloud service  
+   ✅ Removed debug console.log statements
+
+## Current Status
+- ✅ Docker builds successfully
+- ✅ Traefik proxy working
+- ✅ SSL automation ready
+- ⚠️ ffmpeg conversion still needs testing after ARM64 fix
